Subject Re: Indexing PDF and MS Office files
Date Wed, 15 Apr 2015 03:18:35 GMT
Try doing a manual extraction request directly to Solr (not via SolrJ) and
use the extractOnly option to see if the content is actually extracted.

See:
https://cwiki.apache.org/confluence/display/solr/Uploading+Data+with+Solr+Cell+using+Apache+Tika

Also, some PDF files actually have the content as a bitmap image, so no
text is extracted.
